Menus do not appear
Check the startup log for the correct edition ready message and plugin errors. Use a qualified Paper, Purpur or Folia build and a client capable of native dialogs. Try /fmarket and check forgemarket.use. Only one ForgeMarket JAR should be installed. Spigot and Minecraft 1.21.5 or earlier are not supported.
Minecraft 1.21.6 kicks players during menu navigation
Apply the exact internal-button spam exclusion in Compatibility while stopped, then start fully. Do not disable general command protections. Newer supported versions use direct dialog callbacks and need no exclusion.
Offers are not visible
New storefronts start closed. Enable Open for business, check that the offer has stock, and clear search filters. For restocking, hold an exact metadata match. Check blocked materials and creation permissions.
Purchases need a fresh review
Quotes expire after 60 seconds. Changed prices, discounts, balances or stock require a new review. This avoids confirming outdated terms. Premium baskets clear on disconnect or restart.
Cannot collect or deposit items
Use a living Survival or Adventure character. Claims need an empty main-inventory slot and transfer one stack at a time. If an operation is held for review, follow Backup and recovery; do not guess the outcome or repeat manual compensation.
No Vault deposit or withdrawal buttons
The bridge is disabled by default and requires Vault plus a compatible economy provider on Paper/Purpur. It is disabled on Folia. Real provider integration remains unqualified. See Credits and Vault.
Asking for help
Share the edition/version, exact server build, Java and client versions, relevant console error and reproduction steps in Discord. Remove secrets and personal player data before sharing logs. Keep a stopped-server backup before troubleshooting.
